AI-Powered Component Research for PCB Design with Flux Copilot
Optimize Component Selection with AI-Powered Research

Overview
The AI Component Research feature in Flux enhances the component selection process for PCB designs by using AI to streamline research, cost estimation, and validation. This feature simplifies identifying necessary components, evaluating costs and availability, and validating component compatibility within your design.
This process assumes you have already completed the Architecture Ideation step. If not, please refer to the AI Architecture Design tutorial to get started.
Key Benefits
- Selecting Core Components: Identify and search for essential components using detailed requirements.
- Cost Estimation and Supply Chain: Evaluate component costs, check availability, and find suitable alternatives.
- High-Level Design Review: Validate component and architectural compatibility to ensure optimal design performance.
Getting Started
Step 1: Selecting Core Components
To begin, Copilot can help you identify the core components necessary for your project. These are the key integrated circuits (ICs) that drive most of the cost and present the greatest supply chain challenges. Flux Copilot will use both the defined architecture and your project requirements to help you select the best core components.
Identifying Necessary Core Components
Right off the bat, Copilot can provide clarity, insight, and direction to your project by identifying the major components and subsystems necessary. Whether your system needs an MCU and numerous sensors, or a single, highly integrated SoC can meet your needs, Copilot will provide options and specific component possibilities to help you make these decisions.
@copilot, identify the major components and subsystems required for this project, based on the selected architecture.
Pro tip: Copilot is a multi-modal AI, meaning it can also interpret images. You can leverage this feature by adding the block diagram of the final architecture.

Component Search
Flux Copilot uses your company's guidelines, including regulatory requirements, pricing, power consumption, and operating conditions, to find the best components for your specific project needs. By considering these parameters, Copilot ensures that the selected components fit your requirements perfectly.
Copilot also provides a range of options to enhance design flexibility. This breadth of choices allows you to explore different components and configurations, giving you the flexibility to adapt to various design constraints and opportunities.
@copilot, I want to find different alternatives to the converter U3 from different manufacturers. Focus on components that have better temperature stability.
Step 2: Cost Estimation and Supply Chain
Once you've identified some core components, the next crucial step is to validate their cost and supply. A single missing component can sink an entire project, so ensuring availability and affordability is essential. This step leverages Copilot's ability to find alternative parts and Flux's real-time integration with suppliers.
Evaluate Cost and Availability
Use Flux's native cost estimation tools to project your BOM's cost and ensure supply chain coverage. Accesses real-time pricing and availability data through Flux's integration with manufacturer databases, ensuring your components are both under budget and easily sourced.

Find Alternatives
If a component is unavailable or too costly, Copilot can suggest alternatives that meet your requirements, helping you avoid supply chain disruptions:
@copilot, suggest alternative microcontrollers (U1) with similar specifications.
Step 3: High-Level Design Review
After selecting your core components, it's essential to validate each one in depth and ensure that the entire selection aligns with your target architecture. This step is crucial because changing core components at a later stage can result in significant rework, as secondary components might already be chosen based on the initial selection.
Component Validation
Copilot helps you validate each component to ensure it meets your project's technical specifications and regulatory requirements. For instance, you can prompt:
@copilot, validate that the selected microcontroller meets all technical and regulatory requirements for this project.
Architectural Validation
Review the overall architecture to ensure that all components work together seamlessly. Copilot will check compatibility and highlight any potential issues:
@copilot, perform a high-level review of all the components in this project and verify that they match the target architecture. Identify any potential issues.
Best Practices for AI-Assisted Component Selection
- Start with critical components: Focus first on components that drive most of the cost and design constraints
- Consider multiple alternatives: Always evaluate several options for each key component
- Verify supply chain early: Check availability and lead times before finalizing component choices
- Document selection criteria: Keep track of why specific components were chosen
- Balance performance and cost: Use Copilot to find the optimal trade-off between performance and budget
Troubleshooting Common Issues
Component Availability Problems
- If a component has long lead times, ask Copilot for alternatives with similar specifications
- Consider second-source components from different manufacturers
- Evaluate whether design modifications could allow for more readily available components
Cost Overruns
- Use Flux's pricing tools to identify the most expensive components in your BOM
- Ask Copilot for cost-optimized alternatives that maintain required performance
- Consider whether functionality could be consolidated into fewer components
Compatibility Issues
- If Copilot identifies potential compatibility problems, review datasheets for detailed specifications
- Verify signal levels, power requirements, and communication protocols
- Consider adding interface components (level shifters, buffers) to resolve compatibility issues
